The driver, 54-year-old Darryl Lasater of Keyes initially said he had marijuana in the vehicle for personal use, but he later admitted to transporting marijuana, officials said. The deputy then discovered 20 large moving boxes filled with marijuana, the Sheriff's Office said.

On Tuesday, the Calaveras Narcotics Unit searched the van and found that there were more than 200 pounds of processed and unprocessed marijuana inside, authorities said. The street value was estimated at more than $100,000, the Sheriff's Office said.

Lasater was arrested on suspicion of multiple crimes, including possession of marijuana for sale, transportation of marijuana, cultivation of marijuana and driving with a suspended license, authorities said.
